Vanuatu's Prime Minister Joe Natuman may face a vote of no confidence at the end of next week.
Our correspondent reports a motion has been lodged with the Speaker, which, if accepted, could lead to a vote next Friday.
The motion has the backing of 27 of the 52 MPs - the minimum required for such an action.
It has been placed by the opposition leader, Moana Carcasses, but no reasons have yet been given for why he feels the Prime Minister should go.
There were two unsuccessful attempts last month to unseat Mr Natuman.
